Direct oxidation treatment by a novel 3-dimensional electrolytic cell reactor

The\ performance of a novel 3-dimensional electrolytic cell reactor for the treatment of dilute solutions was investigated using different dyes (potassium indigotrisulfonate (PI), Orange 2 and Amaranth) and endocrine disrupting chemicals (EDCs). Continuous experiments demonstrated that the present electrolytic cell reactor was able to directly oxidize the dyes on the surface of the electrode very quickly in response to a change in electric current. It is interesting to note that the energy consumption for the oxidation of PI and Orange 2 was significantly smaller than for the commercially available ozone generators. The electrolytic reactor was also successfully applied to the treatment of trace EDCs including 17β-estradiol, bisphenol-A, nonyl-phenol and chlorinated phenols.
